Set Up Search Criteria

Check the boxes next to the fields you want to search; if you just want to find records that have any value for that attribute, check the box and leave the criteria alone. You can use % or * as a wildcard in the text fields.

Useful Locus Reports

Here are some useful reports that summarize elements of locus data in the database.

All living things are described on a basic level by long strands of DNA. These strands of DNA are broken down into a handful of distinct structures called chromosomes; you can imagine a chromosome being much like a ball of yarn in that it's a tightly-wrapped strand of DNA.

A locus, then, is any particular piece of information that refers to a specific location on a certain chromosome. A locus can refer to a particular location that describes a certain aspect of an organism (a gene), or perhaps just a distinct portion of the chromosome with some unique features (a marker).

What value does studying locus data have?

Studying locus data allows us to generate a strong overall picture of how an organism works. By studying the relative locations of elements on chromosomes and analyzing the differences between the locations, we generate a picture of the inter-relations between genes and other genetic elements and how they work together.

What is the connection between corn and locus data?

The locus data stored here provides information relevant to the study of maize (corn). For instance, we have records (like this one for adh1) that provide detailed information on exactly where a particular element is located in respect to other elements on corn chromosomes; these known sets of distances between loci are called maps. We also provide information on probes, which are genetic tools that are used to specifically locate and describe a particular locus. By combining all of this data together, we can create a very valid picture of specific pieces of maize and learn how to treat corn diseases, improve corn yields, and make corn more nutritious.
